[OpenIndiana-discuss] io errors in rpool, was surprising error when I try to install a package

[Marc Lobelle]

Hi Toomas,

Indeed I have problems with the local storage. This notebook has a 
single ssd drive (rpool) and scrubbing it finds unrecoverable errors

ml at mosquito:/export/home/ml# zpool status -v
   pool: rpool
  state: DEGRADED
status: One or more devices has experienced an error resulting in data
         corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
         entire pool from backup.
    see: http://illumos.org/msg/ZFS-8000-8A
   scan: scrub in progress since Wed Mar  9 18:41:08 2022
         141G scanned at 179M/s, 31,0G issued at 39,2M/s, 142G total
         0 repaired, 21,91% done, 0 days 00:48:07 to go
config:

         NAME        STATE     READ WRITE CKSUM
         rpool       DEGRADED     2     0     3
           c6t0d0s0  DEGRADED     2     0     6  too many errors

errors: Permanent errors have been detected in the following files:

Loosing a few blocks on a 1 TB ssd is acceptable if the OS can avoid 
using these faulty blocks in the future. What does zpool do if I do a 
zpool clear: the faults will disappear from the status but will the 
faulty blocs be avoided henceforth ?

The corrupted files are lost but, if I do "pkg refresh --full; pkg 
update -v", I assume they will be replaced.

However if the faulty blocks are not removed from the list of usable 
blocks, the faults will happen again and the drive must be considered as 
lost and to be replaced
